Loved the shower scene part. Enjoyed playing that very much and picked up on the reference right away. I kept shouting at the TV "I will not give that order!"

Yeah, that was slick. Felt like Michael Biehn for a small second. Dude, that made the game for me; that and other scenes.
MW3 campaigns may not be a puzzle game like Portal but it does well with its cinematic story telling and making you very much involved in that story.
